ADJUSTABLE OPERATING-TABLE;

To allwhomitconcord- 1 Be it known that l" l\'lAX Sonruo'r, a 'citizen oi'the 7 United States, residing at Cincinnati, in the county of Hamilton and State ot Ohi oy have invented certain new and useful Improvements in Adjustable Operating-Tables, of which the following is a specification.

My invention relates to improvements in operating tables for surgical use.

The object of my invention is to provide atable of this character that will combine simplicity, compactsting tables as herein set forth and claimed.

in the accompanying drawings which serve to illustrate my invention: Figure] is a perspective view of the operating table having an elevator and an adjustable hinged leg extension, both shown in raised position. part oi table being broken away to show means for pivoting same to the frame to allow of said table .beingtilted in a 'lrcndelenburg position as indicated by the dotted lines. Fig. 2. is a cross section on the line fZI-.'E showing the mechanism of. the elevator. Fig. 3 is a perspectiveview of the operating table with the various.attaclnnents.adjusted thereon and the adjustable hinge leg extension and elevator lowered. Fig. 1 a plan view of the operating table. Fig. 5 is a perspective view of the removable saddle on the elevator; detached. l ig. G is a bottom view of the top of the table. 'lfiig. 7 is a side view of same. Fig. 8 is an enlarged detail. view showing the pivotal connectiorroi the table with one of the supports. Fig. 9 is a perspective view showing the means of guiding and holding the sliding support for the adjustable hinged leg extension. Figs. 10 and 11 are enlarged top views showing the means for clamping the slotted sliding supports to adjust the top of thetable to the different positions. v Fig 12 is a detailed perspective view of the top of one of the sliding supports. Fig. 13 is a similar 'v iew of the same when pizw'oted to the table top horn the lower inside.

M y adjustable operating table is preferably constructed substantially as follows: An elongated main top 1 preferably made of two castings 2 and 3 riveted together in a suitable manner and bolted tofpivot castings 4 and preferably provided with a covering 5 consisting of sheet iron, brass or glass, is mounted upon a supporting frame 6 comprising legs 7 cross supports 8, 9, 10 and H, bridge l2, pivotal supports 1?- and adjustable supports 14-. The bridge 12 is provided with upright lugs l5 allapted to engagelthe inner sides of the down- Specification of Letters Patent. I I

wardly extending flanges 16 of the top' 1 to hold the top firmly against lateral movement thereof while the bridge 12 provides a support to hold the top firmly in horizontal position when so adjusted. Each pivotal support 13 is provided at its upper end with ayoke bearing 17 adapted to receive the ears 18 integral with the main top 1, and hepivott ly secured thereto by pintle 19 whereby the main top 1 is adapted to be given a tilting movement. Each adjustable support 14 is provided near its upper end with ajournal 20 adapted to engage a bearing 21 upon casting 2, and be secured thereto by spring cotter 22 whereby a pivotal connection is formed between the main top 1 and the adjustable supports 144 The adjustable supports 14 are provided with longitudinal slots 23 which are adapted to receive a screw rod 24 provided upon one end with a head 25 and washer 26 adapted to engage one of the I adjustable supports and upon its other end with wash I ers 27 and 28 adapted to engage the other adjustable support 14 and with threads 29 adapted to receive a hand nut 30 to loosen the washers to permit the rods 14 to be adjusted and to tighten the washers against I said rods 14 to hold the top 1 in any adjustable position desired. The main top 1 is also provided with an adjustable leg extension 31 secured thereto by hinge 32 and adapted to be held in horizontal position by sliding support 33 connected thereto at its upper end by pivots- 34 and having notches 35 near its lower end adapted to engage catches 36 within the keeper 37 secured to the cniss support 8. i

A drain depression 38 is provided near the center of the top and a saddle 39 detachably mounted upon an elevator 40 is adapted to extend over said depression to elevate the body of the patient for the purpose of band-' aging or tor aiding the operator during kidney or gallstone operations. The elevator 40 is constructed with a frame having a cross bar 41 provided with screw bear ings 42, and having standards 43 provided with slots 44 and recesses 45. 'l.he--cross bar 4l holds the standards L shaft adapted to be rotated in either direction andfrom either side of the table to raise or lower said elevator. The elevator is inaintained in a vertical position by means of the adj usi-ing screws 46 and by the ends of the crank shaft 50 and guides Slavhieh extend through the slots 44 of the standards 43.; The upper surface of the saddle 39 preierably formed with a slight down- 43in tixed position relative to eachother and thereby prevents any binding of the elevating mechanism due ward curve and is provided near'its endswith notches 52 to receive lugs 53 of the standards 43 to hold said saddle firmly in place and yet permit of its ready detachment.

My improved adjustable tableis preferably provided with cars 54 each having a thumb screw 55 to receive and hold suitable shoulder braces 57. It is also provided with adjustable leg supports 58.

The top of my improved adjustable table is of pecu-- liar form being oblong in shape and reduced in size at the end near the adjustable leg extension and of the I same width as said extension. This construction effects ,position desired when the washers engaging the adnotches will by gravity engage the catches'36 andhold it in that position until released by raising said justable supports l4 have been loosened by the hand nut 30. i j 4 An adjustable collar 62held by set screw 63 1S secured to the lower end of the sliding support 33 to limit its upward movement.

The operation of my improved adjustable operating table isas follows: To secure the top inthe horizontal position shownin Fig. 1 draw the main top 1. by the handle 60 upwardly until its flanges 16 engage the bridge 12 and lugs 15, then screw the hand nut 30 tightly against the adjacent washer 28 which will secure vit firmly in said position. If the leg extension 31 is in the position shown in Figfd simply draw it upwardly upon its hinge 32 to the position shown in Fig.- 1 when the sliding arm upwardly within the keeper 37 to bring the notches 35 out of the catches 36 when it will assume by gravity the -position shown in Fig. 3. When'the sliding support 33 of the adjustable leg extension 31 is in .'.pivotal engagement with the keeper 37, any move ment of the main top 1 will cause said adjustable leg extension to be moved simultaneously and automatically therewith and especially will a simple movement by'a slight pressure of the hand downwardly upon the ssaeae handle 60, when the adjustable supports 14 have been released, cause the top to be tilted to a Trendelenburg position, as indicated by dotted lines in Fig. 1. ,o

raise or lower the elevator 40 simply turn the handle 61 of the crank shaft while the saddle 39 may be adjusted to the position shown in Figs. 1 or 3 or any other position desired or it may be readily detached when not required for use. p

My improved adjustable operating table is construeted with as few parts as possible and in such a manner as to render it perfectly sanitary. It is especially designed foreonvenience of adjustment from a.

single point as at the handle to almost any position which it is desired to have the main ,top and leg extension assume and at the same time said main top and legeXt-ension may be adjusted independently oi each other if so desired. The elevator and main top may also be adjusted simultaneously or separately as desired. such as to make a strong, compact and convenient adjustable table for the purposes desired. While I have shown and described-a particular construction and arrangement of parts and means for securing them in their several relations I do not wish to be understood as limiting my invention thereto, but

WVhat I claim and desire to secure by Letters Patent is:

1. In an adjustable 'operating table. a supporting frame, I

a top pivotally and adjustably mounted thereon, adjustable supports for said top having sliding engagement with said. supporting frame, a bridge on one end of said supporting frame at a distance from the point oi pivotal support of said top and on which said top is adapted to rest when in normal position, and a lug on top of said bridge at each side thereof adapted to engage 'and steady said top against lateral movement.

2 In an adjustable operating table, a supporting frame; :1 main top mounted 'thereon. a crankshaft supported by said main top, bevel gears on said crank sbafizvertical adjustingscrews supported by-said main top, a bevel gear on each adjustable screw in mesh with a bevel gear on said crank shaft, an elevatorhaving screw bcnrlngs adapted to receive said vertical adjusting screws and having standards adapted to receive and support a saddleut the lop andhavlng a cross bar at their lower ends whereby said standards are connected together. and braced iu fixed rela tion to each other, substantially as set forth.
